Rapid Response Notification System

As the region of Maricopa County strives to meet the federal health limits for dust pollution,
the awareness and actions of every individual can go a long way toward clean air.

Failing to meet the federal health standard for dust [PM10]
pollution threatens public health and ultimately more than $7 billion in transportation project funding for Maricopa County.

You can help to maintain compliance with air quality standards by signing up for notification of a Rapid
Response event. When dust pollution levels begin to rise, the Maricopa County Air Quality Department will send you a message
notifying you of where the pollution hot spot is and what steps you will need to do to help prevent an exceedance of the health standard.

A Rapid Response notification will be sent from one of the following 16 air monitoring locations.

Click on one or more sites listed below to opt in to receive notices when PM10 levels begin to rise in these areas:

How it works:

When a Rapid Response notification is broadcast, the department will ask air quality permit holders with dust generating
activities to inspect their site as soon as possible and employ Best Available Control Measures to stabilize all disturbed soils to reduce
blowing dust.

Air Quality Department inspectors will canvass the area to ensure compliance with its dust control standards.
If you see a dust control issue, give us a call and report the air quality violation at (602) 372-2703 or
file a report online.
